Currently, I have no Blinky,
But I would likely be keen for the Implant that shall not be named because it hasn’t been officially named or announced by Amal yet

The Peer-to-Peer could be a neat little function
Peer-to-peer mode establishes a two-way communication channel between a pair of NFC-enabled devices. When a user brings two devices close to each other, the two NFC chips establish a P2P connection and exchange data.
You probably want to get the attention of an EE like @Devilclarke or @Satur9
@darthdomo may also have an idea or two
